Facebook users have started to change their profile photo to that of Betty the grinning horse, while others have created memes - putting funny phrases over the controversial selfie - and sharing on Facebook and Twitter.

So in homage to Betty's new celebrity status, have a look at our video featuring 'snaps' of her photobombing momentous occasions from the past decade.

Nicola Mitchell, who owns the horse, had threatened to phone Thomson after the image won their Made Me Smile competition, but yesterday, the holiday firm confirmed they will honour the prize.

A spokeswoman said: "We can confirm that despite questions over foal play, Mr Bellis and his family will still be receiving their holiday. And we’re sure they will hoof a good time."
